    Creating energy efficient buildings with Insulated Glass Units

    Australian Glass Group

    Any discussion on the energy efficiency of a building is usually focussed on the importance of ceiling and wall insulation with heat transfer through windows largely ignored.

    Using standard clear glass creates a weak point in the building envelope, often referred to as the ‘thermal wound’, due to the easy transfer of heat through the pane. To counter the thermal wound effect, energy efficient glass products (mainly insulated glass units) are used in many countries worldwide, helping address the window insulation problem.

    Energy efficient glass delivers multiple benefits to a building, especially in increasing the comfort levels when compared to standard glass; the inside environment will be significantly warmer in winter and cooler in summer, minimising the need for artificial temperature control. An energy efficient building also reduces the amount of greenhouse gases produced, contributing to the health of the environment for future generations. This benefit is particularly relevant for commercial buildings.

    From an aesthetic perspective, the use of energy efficient glass products enables buildings to have large glass facades, which can be very appealing. Large glass windows also allow the entry of natural light, creating a feeling of space and being one with the outdoors.

    The right selection and use of glass will allow these advantages without sacrificing the energy efficiency of the building. Insulated glass units, for instance, will help achieve insulation and solar heat gain objectives for any building.
